Wallbox Integration Pause/Resume Error

The switch.wallbox_portal_pause_resume entity in my HA suddenly stopped working today. An error dialog pops saying, “Failed to call service switch/turn_off. 403 Client Error: Forbidden for url: https://api.wallbox.com/v3/chargers/nnnnnn/remote-action”. Would anyone know if there has been a change in the Wallbox API? Would any of you have experienced something similar?

Notes and things I’ve tried:

  • Restarted HA
  • Restarted the Wallbox unit
  • Logged out of and back in to the Wallbox app on my phone
  • I can control max current from the HA integration
  • I am not using OCPP
  • I am the only user of the Wallbox

In my installation, this error occours if I try to switch charge pause/resume when the charger is active but the car is fully charged så the charger is paused for that reason.
I added the check that the wallbox charging power must be > 0 /(indicating it is charging) before switching to pause charge.
